Ring gear question

[chrishewett]

Can anyone tell me if the attatched picture of my ring gear looks as it should?

Bit of a blurry photo, but if you are refering to the bevels/chamfers on the sides of the teeth, yes it should have those! They should be on the side facing rearwards in the car, to help engagement of the standard Lucas starter pinion.

Thanks Matthew,
I was just checking as I have had a problem with a new starter ( see post on +2 forum).

As noted the "lead" (chamfer) should be on the rear of the ring gear so the bendix teeth engage with less friction, the bendix moves forward to contact and drive the flywheel.
The engine when switched off comes to rest in one of four positions due to the resistance of the the compression (four compressions) thus when the starter is operated the bendix turns the engine from one of four positions. (give or take a couple of teeth)
You must check the ring gear teeth around the whole of the circumfrance and four points (90 degrees apart) will show the worst wear, there may be one spot out of the four positions that could have a bad spot (damaged teeth)
